thanks for the advice but i have already tried that and still it doesnt seem to workTry running the troubleshoot the connection wizard and let Kies reinstall the drivers.


Instead of looking for complicated troubleshooting solutions, which takes alot of time and most part dont work, and lots of pains in the a**.....DO THIS (eureka, i discovered this because my battery was dieing, and phone went off):
-unplug your device USB cable
-Swith your PHONE off
-Swith your PHONE on
- Plug it back.
Works for me every time kies goes crazy, and also works no matter what windows version you got.
Thank you.
I report that this method also works for Mac (OS X Lion 10.7.3) and Kies 1.3.0 that was NOT connecting my Galaxy Note anymore with the latest firmware update LB1.

Your message stated that you entered #7284# and got the MMI error. This happened to me also. You have to enter *#7284# and the MMI will run.hey guys,
I too like many of you have had the same problem with my S2 not connecting with kies and ive tried everything that everyone has suggested on this thread from enabling usb debugging mode, to enabling usb debugging mode and disenabling it right after, tried taking both sim and usb out, tried installing windows media player 11, tried the #7284# dial tone procedure (when i dial the number it simply says "connection problem or invalid MMI code"), tried simply turning phone on and off.
however i tried the one method of going into setting>wireless & network> usb utilities and putting it in usb mass storage mode and the drivers run (the little popup that hardware wizard has found your device) but then it prompts me with a message saying
"Reconnect device in Samsung kies (Pc Studio) mode. current connection mode not supported by kies. Check usb setting-> applications-> development-> usb debugging (x))"
i will follow exactly in these instructions and usually the drivers connect just as before but i get the exact same message prompt even though I just did it....it confuses the hell out of me and i dont know what to do! im about to throw my phone out the window! can some please help me with this ive practically tried all of the previous methods and nothing has worked!



This is fast, easy and worked for me!
Dear All
Following are my observations and possible steps to
1. When the phone is upgraded to Android 2.3.4 and above (mine is 2.3.6) Kies stops recognizing the phones and USB connection / Serial port connections etc get reset on the phone
2. Even if proper drivers are there on the laptop (mine is Windows 7 64bit) they are not recognized
3. Device Manager shows "unknown device"
4. Updating the driver also does not result in any help
5. solution lies in the phone
a. key in the dialer *#7284#
b. it has 4 option there..
UART (MODEM/PDA)
USB (MODEM/PDA)
c. For USB. select the PDA.if it already selected to PDA. reselect it by select MODEM and then PDA again.. Only change the USB setting.. andthen press back. try reconnect (thanks to napi1 @ androidforums.com/samsung-galaxy-s2-international/447145-sgs2-kies-not-syncing-os-2-3-5-a.html#post3484588)
6. The Laptop will start recognizing the required drivers and install them
also
Phone is not recognized by laptop when it is in USB debug mode, MyPhoneExplorer does not recognize when it is not in Debug mode
Hope this helps
My setup
Samsung Galaxy S2 GTI9100G (not rooted)
Android 2.3.6 (upgraded on Dec 8th from Samsung link in the phone)
Windows 7 64 Bit
Hello Everyone,
I'm new to this forum, but here goes...
I've read and tried everyone of these suggestions / solutions and none seem to work for me. I do notice something missing though which I'm curious about as it makes me pause everytime I try one of the proposed solutions.... When I plug in my phone via the USB cable (because I have set my USB settings to Prompt what to do) I get a list of options on my phone. I have tried each solution listed here using both "Mass Storage" as well as "Samsung EZUpdater". Now, using "Mass Storage" likely will not work as Kies does not even try and connect to my phone, so I assume I have to use EZUpdater......but no-one above seems to mention this! So, should I be using EZUpdater or not? I have another option available, which is "Media Player" but this does not seem logical either...
I'm pretty frustrated, as is everyone else, with Kies, but I'm still willing to give it a go, so any help would be appreciated...
Thanks.

Hi guys,
First time poster. I've also been trying for the last few months to upgrade to ICS with Win XP. Tried every recommendation on this forum with no luck. Finally borrowed my father's laptop with Win 7, installed Kies and within 40 minutes everything was done. Went to the Samsung website, installed the proper software and right away Kies recognized my SGH-i727R. Didn't have to turn on Debug, no unplugging and replugging the usb cable, didn't have to shut it off and on. Just plugged it in as is and poof! It worked. Anybody using XP might want borrow a buddy's laptop with Win7.
Good luck
